 TCPPING fails to discover initial members if port-range is greater

                 Key: JGRP-1183
                 URL: https://jira.jboss.org/jira/browse/JGRP-1183
             Project: JGroups
          Issue Type: Bug
    Affects Versions: 2.8
            Reporter: Karthik Abram
            Assignee: Bela Ban
             Fix For: 2.10


 I also tested this with 2.10.0.ALPHA4
 I have TCPPING configured this way:
 <TCPPING timeout="3000"
              initial_hosts="localhost[11000],localhost[12000]"
              port_range="3"
              num_initial_members="1"/>
 I notice that if I start up a process on port 11000 and then a second process that binds
to 11001, if the port-range is set to 3 (it seems any port-range less than 8) the
processes successfully find each other. When I set the port-range to 9 or higher, I see
GET_MBRS_RSP responses from the processes with each other's information but nothing is
discovered. I suspect some issue with threading/race-condition. Here is the trace log for
TCPPING with port-range = 50:
